I've trained with a lot of great MMA and BJJ peeps including some BJJ legends.
Lets see but biggest name?
Probably Rickson back in 98. For MMA would likely be BJ Penn or Robbie Lawler. I've been fortunate to train with a lot of notable MMA fighters and BJJ greats only because IMHO, it was really a small circle back then, Now they are big names..back then if you trained with them people would say that's pretty kool, nowadays they say "No way! You trained with Royler Gracie?" Or Royce?
Probably cause I'm getting pretty old.
Wow, hell of a list. You must have some good stories!!
